In future, glass with a recycled proportion of up to 30 percent from car windscreens that can no longer be repaired will be used for the windscreen of the Audi Q4 e-tron. This marks the successful transfer of the "GlassLoop" pilot project to series production.

Together with the two other partner companies Saint-Gobain Glass and Saint-Gobain Sekurit of the car manufacturer Audi, we have demonstrated in the "Glassloop" project how material cycles can be implemented in series production. Over a period of one year, we tested together how new windscreens can be made from defective car glass. Now the process is ready for series production: the car windscreens are shredded in our innovative recycling process and all non-glass components such as adhesive residues are sorted out. The glass granulate obtained in this way is melted down by other partners and it is fed into the manufacturing process for automotive flat glass. The secondary content of the glass produced in this way is up to 30 percent. From September 2023, the windscreens produced in this way will be used for the production of the Audi Q4 e-tron.


The "GlassLoop" project is embedded in Audi's Act4Impact programme for the supply chain. The vision of the programme is to minimise the impact of Audi's supply chain on people and the environment. An approach that has been rewarded: In the category "Recycling Concept", Audi was one of three winners this year of the German Award for Sustainability Projects, a prize awarded by the German Institute for Service Quality, the news channel ntv and the DUP UNTERNEHMER magazine under the patronage of Brigitte Zypries (former Federal Minister of Economics).

We are proud to take an important step towards the Circular Economy and a more sustainable future with this joint project.
